TO ALL WHOM IT MAY CONCERN: y

Be it known that I, L. T. HULBERT, of Painesviile, in the county of Lake, and State of Ohio, have invented a. new and improved Mode for Deiiecting the Bottoms of Tinware Articles; and I do hereby declare that theA following is a full and exact description thereof, reference being had to the drawings accompanying this specitication, and making part ofthe same.

This improvement has for its object deiiecting the bottoms of'tinware articles, such as pans, pails, cans,

Sac., so that the straightness or rigidity thereofn destroyed by the operation of soldering, is again restored. The machines now in use for accomplishing this are imperfect by reason that the operation of soldering cannot be donc until after the process of deilecting, thus rendering the bottoms liable to expand again from the heat of the soldering implement. In my arrangement the proccssof deilecting can be done after the bottom has been soldered; the defect complained of is therefore entirely remedied. I accomplish the deiecting process in such manner that the immediate part only of the bottom to be deflected is touched by the rotary head, thus avoiding any vpossibility of cracking or injuring the soldered joint of the ware; to avoid which, in the other machines spoken of, the operation of soldering must succeed that of the deilecting. The following description will show the construction of my improved deiiecting head, and also explain the particular mode of its operation.

Figure 1 is a perspective view of my ,said improved rotary deiiecting head. 'It is of suitable diameter, and has a thin, smooth rounding periphery, A. It is intended to be attached to my double-seaming machine, for which Letters Patent were granted to me on the 3d day of January, 1860. l

Figure 2 represents the former X of my said machine adapted to Work in combination with the said I rotary head. B is a raised border of suitable width, ori its upper face, as secu.

Figure 3 is a transverse section of the said head and former, showing the precise location where the head impinges on the bottom of the pan as at C, without its touching any other part of the formen The operation is simply to place the Ware to be de'cctcd,4 previously soldered, on thc former, and to bring or lower the head in contact with it, revolvingthe head by the handle of the machine. The said rotarydeflecting head can'be removed from the shaft of the machine when not required for use, so as to allow of other heads for different processes lto be put on the shaft. v

What I claim as my improvement, and desire to be secured by Letters Patent, is-

I claim the use of the independent rotary head, igfl, constructed and operating in combination with the former, g. 2, in the manner substantially as specified and for the purpose set forth.
